XRD spectra of the catalysts were collected using Rigaku Smart Lab SE X-ray diffractometer (Cu-Kα radiation at λ = 0.15406 nm). The average crystallite size of the nanoparticles was estimated using the Debye–Scherrer eqn (1):^{28,34 (link)} where Z is the diameter of the average crystallite size (angstrom or nm); λ is the X-ray wavelength (1.5406 A) for Cu Kα; θ is the Bragg angle; k is the Scherrer constant (typically from 0.9 to 1.0); B is the full width at half maximum.
AFM was used to study the sample's surface morphology and dispersion of Pt nanoparticles on PEDOT:PSS and PEDOT:PSS(EG) using a Nanotec Electronica SPM with and without the EG. The images were processed with WsxM software (v3.1).
The morphology of rGO/PEDOT:PSS(EG)/Pt was characterized by a FESEM (Hitachi, S-4800) and an EDS (HORIBA, EX-250) coupled on the FESEM was used to confirm the component of the rGO/PEDOT:PSS(EG)/Pt.

Microstructural and Optical Characterization

The phases of the product was characterized by XRD (Bruker D8 Advance X-ray diffractometer, Germany) using Cu K_α1 radiation (λ = 1.5406 Å) with a step of 0.02° (2θ) and a scanning rate of 4°/min. The existence of chemical bonds were proven by Fourier transform infrared spectroscopy (FT-IR; Nicolet IR100/200 spectrophotometer, USA) in the wavenumber range 1200–600 cm⁻¹. The microstructure was investigated by field-emission FESEM (Hitachi S-4800, Japan), EDS (Horiba, UK), and TEM/HRTEM (FEI Tecnai G² F20, USA, an accelerating voltage of 200 keV). The PL property was measured using a fluorescence spectrophotometer (Hitachi F-4600, Japan) at room temperature under a Xe lamp excitation.

To examine the structural properties of the pure freeze-dried BC/K.h, and BC/K.h-Nis membranes, as well as BC/Rhiz and BC/Rhiz-Nis membranes, the BC membranes were fractured using liquid nitrogen, attached to a substrate with carbon tape, and coated with a thin layer of gold. The internal microstructure of the BC membranes, with a focus on the impregnation of nisin nanoparticles into the BC matrix, was observed using FE-SEM (Hitachi S-4800 and EDX-350 (Horiba), Tokyo, Japan) at an accelerating voltage of 10 kV at room temperature.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
